fix(ci): remove non-existent sccache version parameter

The previous commit specified version v0.10.2 which doesn't exist,
causing 404 errors when downloading sccache binaries.

Removed the version parameter entirely - the action will now
automatically use the latest stable release (currently v0.12.0).

This fixes the workflow failures where sccache setup was failing with
"Unexpected HTTP response: 404".
